Yes, it's old. Unfortunately nothing has changed. The cousin of a friend here ships containers of goods but I had no idea it would take this long. The good thing is the battery cost $1800 to Miami, about half what a prebuilt one costs elsewhere and all cells matched and tested at more than the advertised capacity from Amy of Shenzhen Luyuan. Delivered in Miami 01 April.
The battery and inverter are now in Managua and getting delivered to my house soon. I'm not sure if it was worth the wait but I should have a complete system for less than $6000. 3200w of panels, 3000w inverter and 10kw/48v of battery. Miami to my house was $300 all inclusive. I wouldn't have a clue how to do all that myself. The one time I got an estimate was for basically a whole house UPS. 1/4 of what I will have for twice the price.
